	* passes.c (init_optimization_passes): Remove references to
	pass_early_new_sra and pass_new_sra.

	* tree-sra.c: Include cgraph.h, tree-inline.h and ipa-prop.h.
	(enum sra_mode): Added SRA_MODE_EARLY_IPA.
	(struct access): Added members bb, stmt, always_safe,
	grp_maybe_modified and grp_scalar_ptr.
	(func_param_count): New variable.
	(encountered_va_start): New variable.
	(encountered_external_throw): New variable.
	(no_accesses_representant): New variable.
	(+no_accesses_p): New function.
	(dump_access): Dump the new access members.
	(sra_initialize): Initialize encountered_va_start and
	encountered_external_throw.
	(get_ssa_base_param): New function.
	(create_access): Caring for INIDRECT_REFs and different handling of
	varialble length accesses in early IPA SRA.  Store tthe basic block and
	stmt - new parameter - to the new access.
	(disqualify_base_of_expr): Take care of INDIRECT_REFs and look through
	SSA_NAMES in IPA_SRA.
	(disqualify_direct_ptr_params): New function.
	(disqualify_all_direct_ptr_params): New function.
	(build_access_from_expr_1): Call disqualify_direct_ptr_params, handle
	INDIRECT_REFs and ADDR_EXPRs.  New parameter stmt passed to
	create_access.
	(disqualify_ops_if_throwing_stmt): Trigger only in intraprocedural
	passes.
	(build_accesses_from_assign): Check statements that are not single
	assignments for disallowed uses of parameters.  Do not create assign
	links in the interprocedural pass.
	(scan_phi_nodes): New function.
	(scan_function): In the interprocedural pass analysis scan phi nodes,
	check for externally throwing statements and va_start, make sure to
	disqualify all direct uses in statement types which arew not handled
	explicitely.
	(build_ref_for_offset): Not static any more.
	(find_param_candidates): New function.
	(mark_maybe_modified): New function.
	(analyze_modified_params): New function.
	(process_dominator_bb): New function.
	(fake_edges_required_p): New function.
	(analyze_caller_dereference_legality): New function.
	(unmodified_by_ref_scalar_representative): New function.
	(splice_param_accesses): New function.
	(decide_one_param_reduction): New function.
	(is_unused_scalar_param): New function.
	(enum ipa_splicing_result): New type.
	(splice_all_param_accesses): New function.
	(get_param_index): New function.
	(turn_representatives_into_notes): New function.
	(analyze_all_param_acesses): New function.
	(get_replaced_param_substitute): New function.
	(replace_removed_params_ssa_names): New function.
	(sra_ipa_modify_expr): New function.
	(sra_ipa_modify_assign): New function.
	(convert_callers): New function.
	(modify_function): New function.
	(ipa_early_sra): New function.
	(ipa_early_sra_gate): New function.
	(pass_early_ipa_sra): New variable.
